Problems solved by technology

[0009] 1.) Silver ions will precipitate out, agglomerating or agglomerating;
[0010] 2.) Silver ions are toxic;
[0011] 3.) Silver ions inhibit the role of CD4 and CD8 in the immune system, which is toxic to the immune system;
[0012] 6.) Silver ions lack an electron, so they are unstable
Imagine that even in the silver colloid obtained by electrolysis, 100% of the silver particles are very small nanoscale silver ions or silver atoms (clusters), but there is no negatively charged stable silver colloid particle, and this silver colloid is almost No bactericidal effect

Abstract

The invention discloses a method for preparing stable electrolytic silver colloid. In the method, nano-silver colloid containing high-proportion stable nano-silver particles is prepared by taking alkaline ionized water prepared from electrolytic water as a dispersing agent. A flow different from the conventional electrolysis method is adopted for distinguishing a circuit of electrolytic silver from a circuit of electrolytic water. Anion water is prepared online by using an independent electrolysis bath, and is injected into the electrolysis bath for serving as a dispersing agent used in preparation of the nano-silver colloid; and each parameter of an electrolytic water generator is adjusted in a way that all silver ions are matched with sufficient hydroxyl ions and are transformed into stable silver colloid particles during the preparation of the nano-silver colloid. The nano-silver colloid prepared with the method has stable quality and a good sterilizing effect, can be widely applied to sanitary sterilization and disinfection of daily articles for human beings, and can be used for disinfecting and cleaning pets.

Description

technical field [0001] The invention belongs to a method for preparing nano-silver colloid, specifically using alkaline ionized water obtained by electrolyzing water on-line or off-line as a dispersant to prepare nano-silver colloid containing a high proportion of stable nano-silver colloid particles. Background technique [0002] The killing effect of nano-silver on germs and viruses is beyond doubt. It is pointed out in the literature that nano-silver can kill more than 650 kinds of bacteria. Its bactericidal mechanism is not to directly poison and kill the bacteria, but to surround the bacteria with a large amount of silver particles. Prompt its cell metabolism to stop, so that the bacteria die naturally. The antibacterial mechanism of nano-silver is summarized as follows: (1) interfere with the synthesis of cell wall; (2) damage cell membrane; (3) inhibit protein synthesis; (4) interfere with the synthesis of nucleic acid; SH) compound, which binds the (-SH) group in ...
